Binocular Cues
Binocular cues are visual signals that help us perceive depth and distance using both eyes. When we look at an object, each eye sees it from a slightly different angle, creating two distinct images. The brain combines these images to gauge how far away the object is, a process known as stereopsis.
Two common binocular cues are convergence and binocular disparity. Convergence occurs when our eyes turn inward to focus on a nearby object, while binocular disparity refers to the slight difference between the images seen by each eye. Together, these cues enhance our ability to navigate and interact with our three-dimensional environment.
